About Sunny Anand

I am a Systems Engineer obsessed with building high-performance, distributed infrastructure.Currently, I am the Founder of Nexus Gateway, a Go-native AI middleware designed to solve the \'Unit Economics\' and \'Security\' challenges of the AI economy. We provide sub-10ms semantic caching and stateless PII redaction for production-grade LLM applications.My expertise lies in Golang, PostgreSQL, and architecting lean systems that scale. I believe that as AI moves from hype to scale, the infrastructure layer must be the foundation of sustainability.

Experience

1. Founder & Lead Engineer

   Nexus Gateway

   Dec 2025 — Present

   Distributed Systems Architecture: Architected a high-concurrency API Gateway using Go(Golang) and PostgreSQL, designed to proxy and route traffic between clients and LLM providers(OpenAI, Anthropic). Semantic Caching: Engineered a sub-millisecond caching layer using Redis (Hot Cache) andPinecone (Vector DB). Implemented Cosine Similarity search to serve cached responses forsemantically similar queries, reducing API costs by 90% and latency by 95%. Universal AI Router:Built a provider-agnostic routing engine that dynamically switches betweenGPT-4 and Claude 3 based on user payloads, eliminating vendor lock-in. SaaS Monetization:Developed a complete billing infrastructure using Stripe Webhooks.Implemented a custom Token Bucket algorithm in Redis to enforce rate limits and automate quotamanagement for thousands of concurrent users. Developer Ecosystem: Authored and published the official Python SDK to PyPI (pip installnexus-gateway) and built a real-time analytics dashboard using Next.js and Recharts.
